Specification of Letters Patent.

Application filed September 18, 1913.

Patented Mar. IO, 1911.4. sei-iai no. 790,462.

To all whom 'it may cof/teem Be it known that I, Henny J. Brummen, a citizen ot' the United States, residing at San Francisco, in the county oit San Francisco and State oli California, have invented a new and useful Dock Structure, ot' which the following is a specification in such full and clear terms as will enable those skilled in the art to construct and use the same.

This invention relates to a dock structure and its object is to produce a resilient fender line ior ships to strike against, while at the same time avoiding the use of the well known spring piles which extend from the mud line to the top of the dock, and which are largely subject to breakage and destruo tion due to marine insects.

It will be understood that while only a small portion of the dock has been shown it may be extended to any desired length.

An embodiment of lthe invention is shown in the drawing in which the same reference numeral is applied to the same portion throughout, but I am aware that there are many modifications thereof.

Figure l is a plan. View of the terminal portion of a narrow dock, and Fig. 2 is a vertical sectional view through a portion of said dock and illustrating the position of the spring fenders.

The numeral l indicates the permanent dock structure which may be of concrete or stone and which is provided with a shelflilre projection at 2. Resting upon the shelf 2 at intervals are a series ot' wear plates 3, upon which the movable fenders slide and which support the girders free from the dock at a plurality of places. Resting upon the wear plates is a built-up girder f5, said girder having vertical sheathing timbers 7 secured thereto and which sheathing' timbers also support two other lines ot' girders 6 and 6".

Embedded in the concrete or stone dock structure l is a series of threaded plates' et, each plate having a bolt 5 threaded thereinto, said bolts extending through the respective girders to prevent them from moving more than a given distance away from the fixed dock structure.

In order to give the necessary resilient effeet to the fenders, very heavy spiral springs 9 are interposed between the fixed dock structure and the fenders, said springs being of such strength as is deemed necessary .to resist the shocks put upon them and be- `ing supported by the bolts 5. In order to prevent the springs :from wearing the doel; and gir-ders, plates l0 are interposed between the ends of th-e springs and the dock and plates l1 between the ends ot the springs and the respective girdcrs. In order to prevent the sheathing from being displaced by side blows, chock blocks 8 are interposed between the several vertical sheathing members 7, those blocks adjacent the bolts 5 having holes therein to permit the fender line to move without bending the bolts.

Having thus described my invention what I claim as new and desire to secure by Iietters Patent 0i the United States, is as follows, modifications within the scope of the claims being expressly reserved:

l. In a dock, a fixed dock structure, a girder slidable on said fixed dock structure, sheathing timbers carried by said girder and extending above the same, another girder connecting the sheathing timbers, springs interposed between the slidable girders and `the fixed dock structure, and means to prcvent the slidable girders from movingmore than a given distance away from the dock structure.

2. In a doek, a fixed dock structure, a ledge projecting therefrom, a girder extending along said dock and resting upon said ledge, sheathing timbers carried by said girder, another girder connecting said sheathing timbers, springs interposed between the girders and the fixed dock struetnre, and means connecting' the fixed dock structure and the movable fender line to prevent the same from moving more than a given distance away :from the dock.

3. In a dock, a fixed dock structure, a supporting ledge extending therefrom, a girder on said ledge and extending along the dock structure, wear plates on said ledge and upon which said girder is slidable, sheathing timbers connected with said girder, another girder connecting thel sheathing timbers, springs interposed between the girders and the fixed dock structure, and means to prevent the movable fender line :trom moving more than a fixed distance away from the dock structure.

4l. In a dock structure, a fixed dock, a ledge extending therefrom, wear plates on said ledge, a girder resting upon said wear plates and slidable thereon, sheathing tim- Ifo' bers Connected with said girder7 another girder connected with the sheathing timbers, springs interposed between the fixed dock structure and the girders, and means extending through said springs to prevent the movable fender line from moving more than a given distance away from the fixed doek structure.

5. ln a dock, a fixed doek structure, a girder slidable on a plurality of supports on said fixed dock structure, sheathing timbers carried by said girder and extendingabove the same, another girder connecting the sheathingtimbers and forming with the sheathing timbers and the other girder, a 15 fender7 and resilient means interposed between the fixed doek structure and fender to hold the girders at a given distance from the doek.

In testimony whereof I have hereunto set my hand this 12th day of August A. D. 1913, in the presence of the two subscribed witnesses.
